This invention relates to packing machinery, and has for its object theprovision of means whereby a vertical stack of articles to be removedfrom a magazine may be fed therefrom so as to permit a continuous conveyor or like device to engage with the lowermostarticle or articlesafter the same has or have been given an initial movement, and to permitthe remaining articles in the stacker to be lowered in the magazine witha minimum of vibration or shock.

The present invention consists of a packing machine wherein means areprovided whereby the lowermost article or articles of a pile arranged ina magazine is or are removed therefrom in such a manner that the speedis gradually increased from rest up to a required maximum.

Further, the present invention consists of a packing machine whereinmeans are provided for supporting the lowermost article of a pile ofarticles in a magazine, and gradually lowering the same into the path ofa device operable to remove the same from the magazine.

Again, the present invention consists of a packing machine wherein meansare provided .for gradually lowering a pile of articles in a magazineand imparting an initial movement to the lowermost article or articlesin a direction transverse to the direction of movement of the articlesin the magazine.

The invention will be more particularly described with reference to theaccompanying drawing which shows a portion of a machine for wrappingcigarette boxes in an outer wrapper of thin transparent paper, and inwhich Fig. 1 is a side elevation of the machine, showing the inventionapplied thereto.

Fig. 2 is a section on the line AA Fig. 1, drawn to a reduced scale, andI Fig. 3 is a diagrammatic elevation similar to Fig. 1 with the partsthereof arranged in a different position.

Referring to the drawing; packets 1 are arranged in superimposedrelationship in a vertical magazine 2 mounted above the bed 3 of awrapping machine, and the packets are removed from the base of themagazine 2 by a pusher piece 4 carried on a chain 5.

In order to prevent the packets dropping with a shock each time thelowermost packet is removed by the pusher piece 4, a pair of cam shapedmembers 6 are provided, one at each side of the magazine which supportthe packets and lower them gradually onto the bed of the machine.

The leading edges of the cam shaped members are so shaped that as theyenter the magazine they move the lowermost packet slowly from rest andaccelerate the same in the direction of movement of the pusher piece 4,and the pusher piece is so timed as to come into contact with the rearend of the lowermost packet when the said packet is moved about half-wayout of the magazine as shown in Fig. 3.

Owing to the fact that the packet is moving at a speed approaching thatof the conveyor the pusher piece engages with the same without shock,and the packet is removed from the machine in such a manner that thecontents are not subjected to any undue vibration.

The pusher piece is constructed as shown in Fig. 2 so as to be capableof passing between the two cam shaped members 6 and gradually pick upthe lowermost packet and move the same through the wrapping mechanism.

\Vhat I claim as my invention and desire to secure by Letters Patentis 1. In apparatus for removing stacked articles from the bottom of amagazine, the combination with a support disposed beneath said magazine,a conveyer arranged to remove articles frorn said support, of means forlowering the articles one at a time from said magazine on said supportinto athe path of said conveyer, and thereafter imparting an initialmovement to the same away from said magazine in the direction ofmovement of the conveyer.

2. In apparatus for removing stacked articles from the bottom of amagazine,the combination with a support disposed beneath said magazine,of a conveying means arranged to remove articles from said support, astepped radial cam having a portion of gradually decreasing radiusarranged to engage the bottom of the lowermost article to position'thelatter on said support in the path of said conveyer, and a followingportion arranged to engage the side of the article and simultaneouslymove the latter with increasing speed away from the magazine in thedirection of movement of the conveyer.

3. In apparatus for removing stacked articles from the bottom of amagazine, the combination with a support disposed beneath said magazine,of a conve er of the continuous pusher piece type or removing articlesfrom said support, means for lowering the articles one at a time fromsaid magazine on said support and into the path of the successive pusherpieces, and thereafter imparting an initial movement to the same awayfrom the magazine in the direction of movement of the conveyer. 4. Inapparatus for removing stacked articles from the bottom of a magazine,the combination with a support disposed beneath said magazine, of aconveying means arranged to remove articles from said support, a steppedradial cam having a portion of gradually decreasing radius arranged toengage the bottom of the lowermost article to position the latter onsaid support in the path of said conveyor, and a following portionarranged to engage the side of the article and move the latter withincreasing speed away from the magazine in the direction of movement ofthe conveyor, the axis of said cam being disposed below the support.

5. In apparatus for removing stacked articles from the bottom of amagazine, the com- )ination with a conveyor disposed immediately beneaththe magazine and moving in a predetermined path, of means iior loweringthe articles one'at a time from said magazine into the path of theconveyor, said means comprising a rotatable radial cam having a spiralportion and an abutment portion, said spiral portion of the cam servingto gradually lower the articles in the magazine, and said abutmentportion serving to engage the lowermost article and impart an initialmovement to the same away from the magazine in he direction of movementof the conveyor, said cam being so positioned with respect to theconveyor that the abutment portion thereof moves substantially in thedirection of movement of the conveyor at the instant of engagement ofthe abutment portion with the article.

In testimony whereof I hereunto aflix my signature.

GEORGE DEARSLEY.
